20．He was admitted to our school two years ago，a top school in our hometown，_____ he has been crazy about reading electronic novels，killing time．（　　）
A．after thatB．since thatC．after whenD．since when

分析 兩年前他被我們學校--我們家鄉的一所重點學校錄取了，從此以后，他一直沉迷于看電子小說來消磨時光．

解答 答案選D
"…he has been crazy about reading electronic novels，killing time"是非限定性定語從句，先行詞是two years ago，所以要用關系副詞when代指two years ago這一時間點；since+時間點，用于現在完成時態，故選D．

點評 本句考查的是非限定性的定語從句，主句與從句通常用逗號隔開．句中"a top school in our hometown"作our school 的同位語．two years ago是先行詞，在從句中與作since一起作時間狀語，從句使用現在完成時．

11．While Jennifer was at home taking an online exam for her business law class，a monitor （監控器） a few hundred miles away was watching her every move．
Using a web camera equipped in Jennifer's Los Angeles apartment，the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room．Her Internet access was locked-remotely-to prevent Internet searches，and her typing style was analyzed to make sure she was who she said she was：Did she enter her student number at the same speed as she had in the past？Or was she slowing down？
In the battle against cheating，this is the cutting edge and a key to encourage honesty in the booming field of online education．The technology gives trust to the entire system，to the institution and to online education in general．Only with solid measures against cheating，experts say，can Internet universities show that their exams and diplomas are valid-that students haven't just searched the Internet to get the right answers．
Although online classes have existed for more than a decade，the concern over cheating has become sharper in the last year with the growth of"open online courses．"Private colleges，public universities and corporations are jumping into the online education field，spending millions of dollars to attract potential students，while also taking steps to help guarantee honesty at a distance．
Aside from the web cameras，a number of other high-tech methods are becoming increasingly popular．Among them are programs that check students'identities using personal information，such as the telephone numbers they once used．
Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones．As in many university classes，term papers are scanned against some large Internet data banks for cheating．

41．Why was Jennifer watched in an online exam？D
A．To correct her typing mistakes．
B．To find her secrets in the room．
C．To prevent her from slowing down．
D．To keep her from dishonest behaviors．
42．The underlined expression cutting edge in Paragraph 3 is closest in meaning toA
A．advanced technique           
B．sharpening tool              
C．effective rule           
D．dividing line
43．For Internet universities，exams and diplomas will be valid ifB
A．they can attract potential students                          
B．they can defeat academic cheating
C．they offer students online help                               
D．they offer many online courses
44．Some programs can find out possible cheaters byA
A．checking the question answering speed                  
B．producing a large number of questions
C．scanning the Internet test questions                        
D．giving difficult test questions
45．Which of the following is the best title of this passage？C
A．The Advantages of Online Exams                          
B．The High-tech Methods in Online Courses
C．The Fight against Cheating in Online Education             
D．The War against the Booming of Online Education．
